  • I am not an electrical enginner, so I am sorry if this is a dumb question. If I use a 3.3V external power source, teensy’s voltage regulator would cause some voltage dropout right? The pinout diagram says 3.7-5.5V for Teensy’s VIN. Would that not affect the Teensy at all? For example, would I get full 3.3V out of digital outputs?

  • Is it OK to power Arduino with TWO of these in series? Also, I looked at LiPower booster/LiPower Shield and it says it boosts the 3.7 volts of the LiPos to 5 volts., but I thought Arduino takes 7-12 volts? Can someone explain this? Thank you.

No public wish lists :(
